Cryptage salt
WebA salt is a string that you add to the user's password to make it longer, and add special characters. This will make bruteforce way more difficult, and most likely the password won't be stored in online database such as ours. WebHasher les mots de passe avec des « salts ». Cette technique consiste en la concaténation d'une ou plusieurs clés (appelées aussi « salt », « seed » ou « graine ») au mot de passe, puis le hashage de la chaine ainsi créée. Bien entendu, la / les clés doivent rester secrètes dans un fichier de configuration de l'application.

It is common for a web application to store in a database the hash value of a user's password. Without a salt, a successful SQL injection attack may yield easily crackable passwords. Because many users re-use passwords for multiple sites, the use of a salt is an important component of overall web application security. … See more In cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase.

With enough compute power and/or storage you can brute force md5 to figure out what the plaintext might have been but it's only one possible plaintext for that hash. It's designed to be both slow and difficult to reverse, and impossible to reverse 1:1. There are known MD5 collisions.

WebAug 1, 2024 · BCrypt is a one way salted hash function based on the Blowfish cipher. It provides several enhancements over plain text passwords (unfortunately this still happens quite often) and traditional hashing algorithms (md5). It wouldn't be accurate to say BCrypt is the best way to store passwords but it should be good enough. WebUnicorn Blood - 200ml 1UNICORN05.

If you actually store MD5 on your database, and don't want to recode your password scheme to use better password hashing techniques, you can add a salt.
